### Common development tasks

**Adding a dependency:**

Assuming you can already build the project, run these in the telegraf directory:

1. `dep ensure -vendor-only`
2. `dep ensure -add github.com/[dependency]/[new-package]`

**Unit Tests:**

Before opening a pull request you should run the linter checks and
the short tests.

**Run static analysis:**

```
make check
```

**Run short tests:**

```
make test
```

**Execute integration tests:**

Running the integration tests requires several docker containers to be
running.  You can start the containers with:
```
docker-compose up
```

And run the full test suite with:
```
make test-all
```

Use `make docker-kill` to stop the containers.
